Description

technical field [0001] The invention relates to an acousto-photocatalytic reaction device and a water treatment process based on three-phase separation. Background technique [0002] With the development of the economy, modern industrial wastewater generally contains a large amount of toxic, harmful, and biodegradable pollutants. If such wastewater is directly discharged into the water body, it will cause serious water pollution. Therefore, it is necessary to decolorize and purify the polluted wastewater. processing becomes critical. Acoustophotocatalytic technology uses light energy and ultrasonic waves as energy sources. It has the advantages of simple operation, mild reaction conditions, and no secondary pollution. It has developed rapidly in the field of water treatment. [0003] Similar to the photocatalytic reaction, sonocatalysis needs to add a catalyst in the reaction tank, and the nanocatalysts tend to agglomerate in water and are not easy to separate. The couplin...
